Title:
HEAT-STORAGE POLYSTYRENE FOAM, PREPARATION METHOD THEREFOR, AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/127990
Kind Code:
A1
Abstract:
The present invention provides a heat-storage polystyrene foam, a preparation method therefor, and application thereof. The method comprises: mixing deionized water, a styrene monomer, a phase change microcapsule, and a first additive to obtain a polystyrene particle containing the phase change microcapsule; adding deionized water and a second additive into the polystyrene particle containing the phase change microcapsule, and performing impregnation to obtain expanded polystyrene containing the phase change microcapsule; and pre-foaming, ripening, and foaming the expanded polystyrene containing the phase change microcapsule to obtain the polystyrene foam. By means of the polystyrene foam prepared with the method of the present invention, the wearing comfort of a helmet is improved, the heat-storage performance of the polystyrene foam is improved, and the addition of the phase change microcapsule also maintains the mechanical property of the polystyrene foam so that the polystyrene foam satisfies mechanical property requirements.
